Mobile Monitoring Reveals Industrial Odor Hotspots in Inner Mongolia

Graphical abstract showing mobile monitoring of odor and VOCs in industrial parks

Industrial odor pollution remains one of the most challenging environmental issues to address. Unlike visible emissions or easily quantifiable pollutants, odors are transient, spatially variable, and often escape detection by conventional fixed-site monitoring stations. A new study published in Atmospheric Environment demonstrates how mobile monitoring technology can transform our understanding of industrial odor emissions, and points toward more effective regulatory strategies.

The Challenge: Persistent Odor Complaints Despite Low VOC Levels

The Tuoketuo Industrial Park in Hohhot, Inner Mongolia, hosts a dense cluster of biopharmaceutical, coal-chemical, and food processing facilities. Despite reporting relatively low total volatile organic compound (TVOC) concentrations, the region has experienced a 15% year-on-year increase in odor complaints. This disconnect between measured pollutant levels and community experience highlights a fundamental limitation of mass-based air quality metrics.

Digital tools for nutrient value chain management in circular wastewater and manure systems

Posted on by cherylmariecordeiro.se

As dairy farms move toward more data-driven nutrient management, near-infrared spectroscopy (NIRS) is emerging as a practical tool. It enables rapid, non-destructive analysis of slurry nutrients directly on-farm, reducing the need for frequent laboratory testing.

However, one key challenge is often underestimated, temperature. Slurry in barns, tanks, and lagoons rarely stays at a constant temperature. It changes with seasons, time of day, and position in the manure management chain. These fluctuations can distort NIR spectra and, if not properly understood, lead to unreliable nutrient predictions.

A recent article in Microchemical Journal by Wang et al. (2025) addresses this issue using advanced spectral methods to examine how temperature reshapes the NIR signature of dairy slurry and what this means for real-time sensing in practice.

How Microalgae Combat Antibiotic Resistance in Wastewater

Posted on by cherylmariecordeiro.se

Microalgae-based wastewater treatment

Our new study, now published in the Journal of Hazardous Materials, reveals promising insights into using microalgae to tackle one of agriculture’s most pressing environmental challenges: the spread of antibiotic resistance genes (ARGs) in livestock wastewater.

The Challenge

Nearly 55% of antibiotics used in China are applied in livestock farming, creating a major pathway for antibiotic resistance genes to enter the environment through farm wastewater. These genes pose serious risks to ecosystems and human health, making their removal from wastewater a critical priority. Similar risks are emerging in aquaculture, where high-nutrient effluents containing antibiotic residues and resistance genes threaten surrounding waters, highlighting the need for robust, nature-based treatment solutions across both terrestrial and aquatic production systems.

An Innovative Approach

Our international research team, including collaborators from RISE Research Institutes of Sweden and China’s Agro-Environmental Protection Institute (AEPI) under China´s Ministry of Agriculture and Rural Affairs (MARA), investigated how the microalga Chlorella pyrenoidosa responds to environmental stressors while treating dairy farm wastewater. Specifically, we examined the combined effects of lead stress and gibberellin (a plant hormone) stimulation on microalgal performance, bacterial communities, and ARG removal.

From Text to Networks: How AntConc and InfraNodus Map the AI-Policy-Governance Nexus

Posted on by cherylmariecordeiro.se

 

  This article reports a methods-focused reading of a curated policy corpus that examines how artificial intelligence (AI), when situated within sustainability-oriented regulation, may be associated with shifts in corporate governance toward stakeholder accountability. The analysis combines corpus linguistics (AntConc) with semantic network techniques (InfraNodus) to move from dense legal language toward a transparent account of recurring concepts and their relations. While any single method has limits, the combined approach is intended to provide both textual evidence and a system-level view, so that substantive claims remain cautious and testable.

Methodology: AntConc and InfraNodus complementarities

  The corpus comprises six (+1 text annex) open-access instruments that, taken together, appear to structure contemporary discussions of AI and sustainability governance across jurisdictions: the EU AI Act, the Corporate Sustainability Reporting Directive (CSRD), the U.S. SEC Climate-Related Disclosure Rule, the EU Green Deal, the OECD AI Principles, and the ASEAN Guide on AI Governance and Ethics. Source PDFs were converted to UTF-8 text, running headers and pagination were removed, article and annex references were preserved, hyphenation was normalized, and domain acronyms (AI, ESRS, SEC, CSRD) were retained to reduce semantic loss.

New publication: EU Water Directives through a Semiotic Lens: Framing Quality, Risk, and Circularity

Posted on by cherylmariecordeiro.se

Cordeiro, C.M. (2025). EU water directives through a semiotic lens: Framing quality, risk, and circularity. Frontiers in Environmental Science, 13:1590166.

The European Union’s water governance framework is widely recognized for its clear legal architecture, offering predictable compliance structures and harmonized standards across Member States. Yet, the language that enables this clarity and coordination may also influence how environmental concepts are interpreted and implemented. Understanding how such language constructs meaning is essential for evaluating both the strengths and limitations of EU water policy.

Beyond Compliance: The Power of Language in Policy

EU water law not only regulates environmental behavior; it also plays a constitutive role in shaping how key policy concepts such as quality, risk, and circularity, are defined and operationalized. This study applies a triadic semiotic framework, drawing on Greimassian structuralism, Social Semiotics, and Ecosemiotics, to examine 11 foundational EU water directives, including the Water Framework Directive, the Nitrates Directive, and the Water Reuse Regulation. Through this lens, the analysis explores how regulatory texts frame environmental priorities, assign agency, and embed specific worldviews that influence implementation and policy outcomes.

Microalgae and EPS for Mitigating Antibiotic Resistance in Livestock Wastewater

Posted on by cherylmariecordeiro.se

Antibiotic resistance is one of the most pressing challenges in both environmental and public health domains. A growing body of research is exploring nature-based solutions to mitigate the spread of antibiotic resistance genes (ARGs), particularly in agricultural systems. A new study published in Bioresource Technology contributes to this field by examining the potential of microalgae and extracellular polymeric substances (EPS) to reduce ARGs in livestock wastewater.

Overview of the Study

The research, led by Xiaoyu Xu and a multidisciplinary team from China and Sweden, investigates the interactions between algae and EPS and their role in mitigating the spread of ARGs in contaminated livestock water. As the agricultural sector is a known hotspot for antibiotic use and discharge, developing effective treatment strategies is both urgent and impactful.
